Oh, I totally forgot about the ROM-specific config screen. I've never thought to use it since there isn't an easy aceess button ready to go in the N900 version of MAME. Thanks for reminding me.

All the same, shouldn't there be a global key that can be set? I'm thinking of Spy Hunter too, now, and Radmobile, Turbo Outrun,etc. I'd really like to just handle this all at once, instead of per ROM, if I could.

As to framerates, Outrun gets pretty playable at ~ 4-5 frameskip, once you get past the checkered flag bit, you should try it. (But, I kind of like playing these games at a slightly slower clip, it makes 'em easier! %^)
